Tiny Implementation of Conway’s Life…

March 22, 2015 | Arduino, Embedded, My Projects, My Stories | By: Mark VandeWettering

I had a few minutes, so I thought I’d try making a graphics demo that runs on the tiny little 0.96″ OLED display I mentioned last week. One of the first programs I ever wrote was an implementation of Conway’s Game of Life, having learned about it from Martin Gardner’s Mathematical Games column in Scientific […]

My first try at an inexpensive 0.96″ OLED display…

March 17, 2015 | Amateur Science, Arduino, Development Boards | By: Mark VandeWettering

As my recent video showed, I have a lot of development boards. I also have a fair number of little boards that are useful to plugin to these development boards to accomplish various tasks. Yesterday, I received a little OLED board that I thought I’d try hooking up and let you know about my experience. […]

A 6M beacon using the NT7S’s Si5351 board…

March 9, 2015 | Amateur Radio, Arduino | By: Mark VandeWettering

This morning, the Tweeti-verse (I can’t believe I just used that word) informed me that Thomas, LA3PNA had constructed a VHF beacon using the Si5351, and I was tagged as somehow helping: VHF beacon with the Si5351. code: https://t.co/OkgZXKFSKc , video: http://t.co/hbZl9F76Aj based on code from @brainwagon @NT7S — Thomas S Knutsen (@la3pna) March 9, […]

A Big Bin Full O’ Development Boards at BrainWagon Labs…

March 1, 2015 | Arduino, Atmel AVR, Hardware, My Projects, Raspberry Pi | By: Mark VandeWettering

I have an odd obsession with small, relatively cheap hardware development boards. Over the last few years, I’ve acquired a bunch of them, from Arduino to Raspberry Pi to BeagleBone Black. I thought it might be nice to just do a short video showing what I have around. So I did. Here’s a little 25 […]

Task completed: Evil Mad Science ISP Shield soldered together…

February 24, 2015 | Arduino | By: Mark VandeWettering

Last night, the absent-far-too-often urge to fire up the soldering iron and make something hit me, so I warmed up the Weller and did this: Soldered one of @EMSL ISP shield kits together tonight, and burned a bootloader on 328. #babysteps pic.twitter.com/0vXo2Wewie — Mark VandeWettering (@brainwagon) February 24, 2015 I bought this kit quite a […]

FTDI-gate…

October 24, 2014 | Arduino | By: Mark VandeWettering

My hardware hacking friends have been all a-twitter (and all a-pick-your-favorite-social-platform) about recent actions by FTDI. In case one of my three or so regulars haven’t heard about this dust-up, here’s a brief synopsis. FTDI makes a series of chips which translate between USB and either RS232 serial or TTL level serial signals. These chips […]

Nifty Arduino/AVR hack: measuring VCC

In my previous article pondering sensors for my garden, I shamefully neglected a viable and interesting choice, the JeeNode

Pondering some sensors for my garden…

June 19, 2014 | Arduino | By: Mark VandeWettering

We’ve started a garden at our house in a pair of raised beds. I’ve been pondering about possibly creating a set of sensors to monitor the dryness of the soil in the beds as well as in the container that I have a dwarf Meyer lemon tree going in. I was trying to figure out […]

My Arduino bumper, with actual prints!

March 23, 2013 | 3D, 3D printing, Arduino, My Projects | By: Mark VandeWettering

Okay, our Replicator 2 went back online this week, and I decided to give printing my Arduino bumper another try. Since the last time, I have revised the program and code a couple of times. I was concerned that the various bits of solder protruding from the bottom of the board would need extra relief […]

Another stab at an Arduino bumper…

March 9, 2013 | Arduino, My Projects | By: Mark VandeWettering

Earlier this week, I tried to print out the first version of my Arduino bumper. Sadly, our Replicator 2 had a malfunction mid print, and it’s still offline (a problem with the temp sensor) but that doesn’t mean I’ve been entirely stationary. I mentioned on twitter that I was having trouble using the minkowski operator […]

Arduino Bumper Shell, created with OpenSCAD

March 2, 2013 | Arduino, My Projects, Raspberry Pi | By: Mark VandeWettering

Last week, I got a chance to experiment with a Replicator 2, and printed some brackets for my robot project. I designed them using OpenSCAD, which is kind of a scripting language for solid shapes. It can export in STL format, which I then used MakerWare to drive the Replicator 2. The picture at the […]

PIR sensor from TAUTIC.COM

February 23, 2013 | Arduino, My Projects | By: Mark VandeWettering

A few days ago, I heard that Jayson Tautic (@tautic), manufacturer and purveyor of a interesting electronic prototyping goodies, had put up an interesting offering: a small PIR (passive infra red) motion detector. I’m always up for a new sensor to play with, so I ordered a pair for fun, and they arrived on Friday. […]

Some small experiments with Arduino sound…

November 29, 2012 | Arduino, My Projects | By: Mark VandeWettering

Last year, I spent a little bit of time to create a set of blinking Christmas lights that I could mount in a hat. It was powered by an ATtiny13 and mounted in an Altoids tin. While setting up my Christmas tree last weekend, I found them, and they still work. In case you missed […]

ArduinoSudoku – sudoku on arduino

July 26, 2012 | Arduino | By: Mark VandeWettering

Just a quickie Arduino project that I ran across this morning: Sudoku on the Arduino. It’s pretty cute, since it uses the Arduino tvout library to generate video, meaning that you can display and play on your TV set. Neat! The only real description of the project is inside the zip file which you can […]

The first Internet of Things Bay Area Meetup and the Air Quality Egg…

March 29, 2012 | Arduino, Internet of Things, Microcontrollers | By: Mark VandeWettering

Last night, I met with Nanode creator Ken Boak and Chris Jefferies from tinajalabs.com at Cafe Actual in Berkeley for the inaugural IoTBayArea meetup. IoT groups are already going strong in many cities like London, Amsterdam, and NYC, but now that Ken is operating here in the SF Bay Area, he wanted to get a […]
